part on order chase

A part already ordered with a known ETA is chased, not reordered — and a chase is worthless without chase_after, because nothing else will wake this job up.

The answer conformed to the contract and every assertion held.

What the model was given

System instructionassembled from the contract schema, not hand-written

You own this job for its whole life. A step cannot be performed. Decide what now happens to the job, the machine, the customer booking and the parts order. You may be woken days from now, so anything you need later must be written down here.

Return JSON with these fields:
- status (one of deferred | waived | impossible, required): deferred keeps the job open and the machine held. waived requires a named person with standing and releases the machine. impossible seals deficient and files a procedure defect.
- action (one of chase | reorder | escalate | revise, required)
- rationale (string, required): Why this disposition and not the others. This is read by a person in a dispute months later.
- chase_after (string, null when it does not apply): ISO 8601 UTC. When to wake and check. Required when action is chase.
- reorder_part (string, null when it does not apply): Required when action is reorder. A purchase order is DRAFTED, never sent.
- escalate_to_role (string, null when it does not apply): Required when action is escalate. The role that must decide, not a person's name.
- hold_machine (boolean, required): Your recommendation. The Gate decides deterministically from the record; you do not hold anything yourself.

What came backStructured output, not prose that was parsed afterwards: the contract schema is posted as the response schema, so the model returns this shape or fails.

{
  "status": "deferred",
  "action": "chase",
  "rationale": "The required EBC FA388HH front brake pads are currently out of stock but are already on order under PO-2210, with an expected supplier ETA of 2026-08-20. Since the customer collection is booked for 2026-08-21, we will defer the job and hold the machine. We will set a chase date for the morning of 2026-08-20 to verify the delivery of the parts so the service can be completed on time.",
  "chase_after": "2026-08-20T09:00:00Z",
  "reorder_part": null,
  "escalate_to_role": null,
  "hold_machine": true
}

What this scenario asserted

Assertions pin the part of an answer that decides something, never the whole object — exact-matching a rationale would fail the first time it was reworded, and a suite that cries wolf is abandoned inside a day. Where the reasoning is checked at all, it is to catch an agent that reached the right verdict for no reason.
